I was curious if 80% was max you can get with heroes , since the ability of the elves gives 7% more to resistances and I'm wondering if it works or if it's not .Like is the cap for stats 80 but the extra 7% applies, or it's 80% and the ability is useless now?

Yust leveling my hero up and reached level 44 so far. With my human hero i already maxed devensive to 80/80/80 which is the same as your elven level 60 hero. So I think this is the top devensive for all heroes, elf, himan and orc.
